Definitions

  • the invention relates to a method of and a device for eifecting the quick drawing-0E with low resistance and free from loops or kinks of yams from a yarn pack placed before or in a yarn-processing machine, e.g., a weaving machine, a loom or knitting frame or any other appliance for treating yarns in order to handle the greatest possi ble quantity of yarn in the shortest time, uninterruptedly, without impediment, and free from knots.
  • a yarn-processing machine e.g., a weaving machine, a loom or knitting frame or any other appliance for treating yarns in order to handle the greatest possi ble quantity of yarn in the shortest time, uninterruptedly, without impediment, and free from knots.
  • the yarn When the yarn is drawn off over the head of the spool, whether it is in the form of a cylinder, a cop or a cheese, while the yarn carrier is not rotated, the yarn tends to ball while being drawn off, this ball varying in size with the drawing-0E speed and the varying spool diameter, thus causing considerable differences in the yarn tension, which likewise give rise to irregularities in the handling or working of the yarn.
  • Drawing out of spinning cans in which the yarn is laid loose in regular or irregular coils can only be done slowly, if balling, or the drawing of bunched coils not running out in a smooth thread is to be avoided.
  • the quantity of yarn which can be put in a spinning can is also in practice relatively small.
  • the yarn pack is of a known form in which a plain strip of yarn formed of transversely extending, elongated loops of yarn is spirally wound up together with a plain separating strip into a roll.
  • the yarn being drawn off in the longitudinal direction of the strips, after the loop of the yarn to be next withdrawn has been brought to a spatially fixed point by the motion of the yarn pack and has been exposed by or released from the separating strip.
  • the rollshaped yarn pack formed of a layer of yarn coils or windings and a separating strip is rotatably mounted and means is provided for drawing oil the separating strip at a fixed point and simultaneously rotating the yarn pack.
  • Especially suitable yarn packs for this purpose are those in which the yarn coils consist of elongated, helically wound turns over-lapping each other.
  • Such yarn packs are quickly and easily wound by machinery. Their weight is not increased by separate spool or bobbin elements and they can be made to contain a very large quantity of yarn which can be drawn off to the very end without tangl-ing.
  • the axis of the yarn pack is shifted as its diameter decreases so that the yarn is drawn otf always at the same level.
  • the rolled yarn pack is either supported circumferentially on a drawing-elf table which simultaneously supports the freed yarn coils or the axis of .the roll is raised or lowered by a control element making contact with its circumference, driven by a reversing motor, as its diameter decreases.
  • FIG. 1 is a side elevation of the drawing 01f device with a separating strip moving vertically upwards
  • FIG. 2 is an end View corresponding to FIG. 1,
  • FIG. 3 is a perspective view of the yarn pack for the device with the separating strip being drawn 01f vertically, and the yarn thread being drawn off horizontally;
  • FIG. 4 is a perspective view of a control element for the shaft of the yarn roll or pack
  • FlG. 5 is a perspective view of a second embodiment
  • FIGS. 6 and 7 show further embodiments of the braking and separating element.
  • the body of the device consists of a base 1 (FIG. 1), a central sup- 'rollers 13 is permanently t'ensioned.
  • FIG. 2 3 porting partition 2 (FIG. 2), a front plate 3 parallel thereto, and side plates or braces 5, 6 (FIG. 1).
  • the yarn pack 7 is carried in the lower part of the device and consists of a strip of coiled yarn 8 and a separating or parting strip 9; which, as will be seen in FIG. 3, are rolled up together to form a yarn roll 10.
  • the layer of coiled yarn consists of yarn coils 11 (FIG.
  • the drive for exposing the coiled yarn is supplied by a separate driving motor so that the yarn being drawn oif is itself free from all forces required for its exposure, the motion of the yarn pack, and overcomes the friction between the thread being drawn and the rest of the yarn in the pack.
  • the handling and processing of the yarn can, therefore, be conducted with a completely uniform, but also very low yarn tension; in fact, so low, as to be exactly suiiicient to keep the yarn approximately straight.
  • the separating strip 9 is led overa guide roller 12 upwards.
  • This strip runs between two, gearmeshed, counter-rotating driving rollers 13, by which it is drawn off the yarn pack roll 10, and finally wound on the stock reel 14'.
  • This reel 14 is driven through a chain sprocket 15 by a chain 16, running on a sprocket 17.
  • the stock reel 14 is connected with the sprocket 15 by means of a slipping clutch 18;
  • a chain sprocket 20 on the yarn-processing machine is continuously driven by the latter at a speed corresponding to the instantaneous rate of yarn consumption by the said machine. It is connected by a chain with the chain sprocket 19 of a chain drive 21, controlled or driven by the sprocket 20. This gear transmits the drive, through a reducing train controlled by the handle 22, and a drive sprocket 23 actuating a chain 24 to the chain sprocket 17, which is connected with the upperdriving roller 13.
  • the separating strip 9 is drawn off the roll according to the rate of consumption of the yarn by the processing machine and correspondingly frees or exposes 1 and 17 are equal and the diameter of the stock reel is somewhat larger than that of the upper roller 13 so that the part of the strip 9 between the stock reel 14 and the
  • the driving force of the slipping clutch is set at such a low value that the separating strip 9; cannot be drawn through the rollers 13 force of the slipping clutch 18 will be overcome and the strip 9 always be reeled up under tension.
  • the yarn consumption of the processing machine may fluctuate over short or long periods, regularly or irregularly.
  • the longer fluctuations are taken up by controlling the chain sprocket 20, while for dealing with the shortterm fluctuations, it is advisable to accumulate in front of the fixed yarn-guiding means 28 (FIGS. 5, 6) which forms a part of the processing machine, a sufficient number of exposed or freed yarn coils or loops 11, by which means the small and medium, periodic fluctuations of the rate of consumption of the yarn in the processing machine can be compensated.
  • the diameter of the yarn pack roll 10 continuously decreases, so that the point of release of the yarn coils or loops descends. To ensure that these yarn coils are always released at the samelevel as well as to ensure that when a new yarn pack is inserted this level is maintained,
  • the axis (FIG. 3) of the pack is correspondingly raised or lowered.
  • the axis 25' is rotatably supported in a slide 29 (FIG. 4) which can be moved up and down in vertical guides 31 by means of a screw spindle 32.
  • This screw spindle is linked through a pair of bevel gears 33 (FIG. 1) to a small, reversing motor 34, which, through a two-way switch 35, can be set to runin either direction.
  • the two-way switch coacts with a stop 36 on a bell-crank lever 38 pivoted in the body, and carrying the previously mentioned guide roller 12.
  • the yarn roll diameter decreases, its axis 25 is raised by the spindle 32, and the motor 34 is stopped as soon as therelease point has reached the prescribed height. If the diameter of the yarn roll is greater than the corresponding position of the axis 25, the other contact of the two-way switch is brought into action and the spindle 32 rotated by the motor 34- 'in the opposite direction until the yarn-release point is again in the prescribed position.

  • the coiledyarn it) lies with its circumference on a run-off table 49.
  • This table 49 also carries the withdrawn portion of the separating strip 9 and the exposed portion of the yarn coils 11 not yet withdrawn by the yarn processing machine.
  • This arrangement automatically ensures that the release point for the yarn coils is always at the same meight, viz., at the level of the upper surface of the ele- It is here, therefore, unnecessary to provide special means for controlling the height of the axis 25 of the yarn roll; it being sufficient to make it guidable in vertical slots 51 of guide plates 52 attached laterally to the run off table 49.
  • small spindles 54 are supported between pairs of brackets 53 on the run-off table 49, carrying light braking elements 55, which are by means of small weights 5'7 slidably carried on arms 56 attached on the spindles 54, controllably pressed against the exposed or released yarn coils ⁇ or loops 11.
  • These braking elements 55 are thin strips of metal or plastic foil, flexibly curved and highly polished on the underside, which have the purpose of lightly pressing the yarn coils against the polished surface of the run-off table.
  • the two braking elements of each pair are reciprocally spaced at a distance continuously diminishing in the direction of run-off, whereby it is attained that the drawing tension on the threads is greater on the coils nearest the yarn guide 28 and the thread is straight when it reaches the said guide 28,
